Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a cutting device for a radioactive isotope applicator. Background Technology

[0002] A radioisotope patch (applied patch) is a medical device used to treat keloids. This patch is applied tightly to the surface of the lesion and uses short-range beta rays emitted by the isotope to perform localized superficial radiotherapy in order to destroy the lesion tissue.

[0003] Currently, the main radioactive isotopes used clinically are the solid radioactive source Strontium-90 and the liquid radioactive source Phosphorus-32. The Strontium-90 applicator consists of a rubber sheet with holes cut to match the shape of the affected area. During treatment, the applicator is applied to the patient's skin, aligning the holes with the affected area, and finally, the Strontium-90 radioactive source is placed on top of the applicator. The Phosphorus-32 applicator, on the other hand, involves cutting a piece of filter paper to match the shape of the affected area, applying Phosphorus-32 solution to the filter paper, sealing the filter paper, and then applying the Phosphorus-32 applicator to the affected area.

[0004] Whether it's a Strontium-90 or Phosphorus-32 applicator, imprinting and cutting is the first and most time-consuming step in the manual preparation of the applicator. The applicator needs to be very close to the size of the patient's affected area, and cutting it into the corresponding shape consumes a lot of the department's human resources. Manual cutting is inefficient; it also increases the risk of cutting one's hand during the cutting process; moreover, doctors need to have direct contact with the skin of dermatologists, which poses a possibility of infection.

[0005] Furthermore, phosphorus-32 applicators are expensive and have complex preparation processes; while strontium-90, due to its solid properties and longer half-life, is often used for the treatment of small-area, cost-sensitive patients. However, existing equipment and processes only support the preparation of single isotope applicators and cannot simultaneously accommodate phosphorus-32 filter paper cutting and strontium-90 protective card forming, requiring hospitals to configure corresponding equipment separately, making it difficult to achieve equipment sharing and cost-effectiveness.

DETAILED DESCRIPTION

[0030] The following is a specific embodiment of the utility model combined with the drawings, which further describes the technical scheme of the utility model, but the utility model is not limited to these embodiments.

[0031] As Figures 1 to 6As shown, a radioactive isotope applicator cutting device includes: a motion mechanism, on which a cutting tool 200 is mounted, the motion mechanism being able to drive the cutting tool 200 to move within a three-dimensional workspace; and a cutting base plate 100, the cutting base plate 100 being divided into a first cutting area 110 for cutting filter paper and a second cutting area 120 for cutting rubber sheets, the first cutting area 110 and the second cutting area 120 being located directly below the three-dimensional workspace.

[0032] The motion mechanism has movement along three axes: X, Y, and Z, thereby driving the cutting tool 200 to perform cutting. The cutting base plate 100 is divided into two distinct areas: a first cutting area 110 and a second cutting area 120. The first cutting area 110 is specifically used for cutting filter paper, while the second cutting area 120 is used for cutting rubber sheets. Both the first and second cutting areas 120 are located directly below the motion mechanism's active area (i.e., the three-dimensional workspace), allowing the cutting tool 200 to cut in either the first cutting area 110 or the second cutting area 120.

[0033] The core concept of this design is to eliminate other functional modules of the entire process equipment (such as medication application, drying, and sealing), retaining only the core function of high-precision cutting. By separating the core cutting function, manufacturing costs are reduced. Simultaneously, this cutting device can plan the cutting path based on the contour data of the affected area, thereby automatically cutting filter paper sheets of the corresponding shape or cutting holes of the corresponding shape into rubber sheets.

[0034] It should be noted that, for the phosphorus-32 patch preparation process, the cut filter paper can be automatically processed by placing it into the subsequent dispensing, drying, and sealing devices. This method, through modularization, covers the entire phosphorus-32 patch preparation process in a low-cost, progressive manner, thereby achieving the goal of cost reduction and efficiency improvement.

[0035] The filter paper can also be manually dripped, dried, and sealed. Therefore, this device is very flexible in application.

[0036] In addition, this equipment supports the cutting of filter paper (phosphorus-32 applicator) and rubber sheet (strontium-90 applicator). Through replaceable cutter head, adaptive pressure control and other technologies, it ensures the precise cutting of different materials. The preparation needs of phosphorus-32 applicator and strontium-90 applicator can be met by a single equipment.

[0037] The preparation process of the applicator is as follows:

[0038] 1. Use a depth camera to capture a model of the patient's body surface, outline the affected area in the model, and then perform dimensionality reduction to obtain the contour data of the affected area (or use a flexible material to directly imprint the affected area on the patient's body, and capture the contour data of the affected area under a distortion-free top camera).

[0039] 2. In the integrated planning system, the outlines of multiple affected areas are placed in one plate;

[0040] 3. Load the adhesive plate 300 and the required materials (filter paper or rubber sheet) into the equipment, then input the contour data into the equipment. The motion mechanism drives the cutting tool 200 to cut on the material along the predetermined trajectory. After the cutting is completed, remove the adhesive plate 300 and the material, remove the waste paper to obtain a filter paper sheet that conforms to the shape of the affected area or a rubber sheet with holes in the shape of the affected area.

[0041] It should be noted that in step one, the contour data of the affected area can also be obtained through other means, as long as the contour data of the patient's affected area can be obtained.

[0042] like Figure 6 As shown, based on the above embodiment, it also includes an adhesive plate 300. One side of the adhesive plate 300 is configured as a first adhesive surface 310 for fixing the filter paper or rubber sheet to be cut. The adhesive plate 300 is detachably connected to the cutting base plate 100. The first adhesive surface 310 is located directly below the three-dimensional working space.

[0043] The adhesive plate 300 is an auxiliary tool whose main function is to fix the material to be cut (filter paper or rubber sheet) on an adhesive surface to ensure that the material does not shift or deform during the cutting process. By firmly attaching the material to the adhesive plate 300, material slippage caused by the pressure or movement applied by the cutting blade 200 can be avoided, thereby improving cutting accuracy. The adhesive plate 300 is detachably connected to the cutting base plate 100, which means that the adhesive plate 300 can be installed on the cutting base plate 100 before cutting and removed from the cutting base plate 100 after cutting.

[0044] Example 1:

[0045] In Embodiment 1, the other side of the adhesive plate 300 is set as a second adhesive surface 320, and the adhesive plate 300 is bonded to the cutting base plate 100 through the second adhesive surface 320.

[0046] When the adhesive plate 300 is placed on the cutting base plate 100, the adhesive plate 300 can be fixed to the cutting base plate 100 by the adhesive action of the second adhesive surface 320. It is also very convenient to remove, as the adhesive plate 300 can be removed directly.

[0047] Example 2:

[0048] In the second embodiment, the other side of the adhesive plate 300 is connected to the cutting base plate 100 by a snap-fit ​​structure, a pin structure, or a magnetic attraction structure.

[0049] The back of the adhesive plate 300 can be quickly fixed to the cutting base plate 100 by means of elastic buckles; or the adhesive plate 300 can be inserted into the fixing hole on the cutting base plate 100 by means of pins to achieve a stable connection; or a magnet or magnetic material can be used to form a magnetic attraction force between the adhesive plate 300 and the cutting base plate 100 to make the two firmly bonded.

[0050] like Figures 1 to 6 As shown, based on the above embodiments, it also includes a housing 400, which is configured as a box-shaped structure, and the motion mechanism and the cutting base plate 100 are both located inside the housing 400.

[0051] Based on the above embodiments, the outer casing 400 includes a housing 410 and a top cover 420. The top of the housing 410 has an opening 411. The top cover 420 is rotatably mounted on the housing 410, and the top cover 420 can be closed to cover the opening 411 or opened to expose the opening 411.

[0052] The top of the housing 410 has an opening 411, serving as a passage for the adhesive board 300 to enter and exit the housing 410. The top cover 420 is mounted on the top of the housing 410 via a hinge or other rotating mechanism. This design allows the top cover 420 to be flexibly opened (exposing the opening 411) or closed (covering the opening 411), thereby controlling the opening and closing of the interior space of the housing 410. When cutting, closing the top cover 420 creates a sealed space inside the housing 410.

[0053] like Figures 1 to 3 As shown, based on the above embodiment, the motion mechanism includes a CoreXY motion element 500 and a Z-axis motion element 600. The CoreXY motion element 500 is installed inside the housing 410, the Z-axis motion element 600 is installed on the CoreXY motion element 500, and the cutting tool 200 is installed on the Z-axis motion element 600.

[0054] CoreXY is a two-dimensional planar motion system that controls movement along the X and Y axes via two synchronous belts and four pulleys (typically two fixed pulleys and two movable pulleys). When the motor drives the synchronous belts, a specific path design allows the Z-axis motion element 600 mounted on them to move arbitrarily in the XY plane. The Z-axis motion element 600 controls movement in the vertical direction (i.e., the Z-axis). The Z-axis motion element 600 can raise or lower the cutting tool 200 and move it along the Z-axis to the desired height to meet the cutting requirements of materials of different depths or thicknesses.

[0055] Based on the above embodiment, the cutting tool 200 is configured as a dragging structure. The motion mechanism drags the cutting tool 200 to move, thereby cutting on the filter paper or rubber sheet.

[0056] like Figures 1 to 4 As shown, based on the above embodiment, a leveling mechanism is provided at the bottom of the box 410. The leveling mechanism includes four leveling bolts 412, which are connected to the four corners of the cutting base plate 100. A spring is provided between the leveling bolts 412 and the bottom of the cutting base plate 100.

[0057] Four nuts are provided at the bottom of the housing 410, and four leveling bolts 412 are connected to the four nuts respectively. By turning the adjusting bolts, the height of the cutting base plate 100 can be adjusted. The cutting base plate 100 elastically abuts against the housing 410, thereby applying an upward elastic force to the cutting base plate 100. The leveling mechanism can level the cutting base plate 100 to ensure it is in a horizontal state, thus providing cutting accuracy.

[0058] like Figure 1 , Figure 4 , Figure 5 As shown, based on the above embodiment, a mounting bracket 413 is provided between the bottom of the housing 410 and the cutting base plate 100, and the main board 414 and power supply 415 are installed inside the mounting bracket 413. This design makes the device more compact, thereby reducing its size.

[0059] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0060] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0061] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0062] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
